• Laser Beam Welding
  frequency, the beam of a neodymium YAG laser (l.06 micron wavelength) will pass through quartz lenses, clear plastic or glass and other transparent materials. However a carbon dioxide laser emitting a beam with a wavelength of 10.6 microns will not pass through the quartz lens etc. but rather...
• Welding
  . Combinations of shielding gas, power source, and electrode significantly affect metal transfer across the arc. A variety of gases are used, depending on the metals reactivity and the joint design. For example, argon is used most often, though carbon dioxide is added when welding ferrous metals. Carbon...
• Fiber Laser Welding of Fuel Cells
  waste products with most fuel cells are water and in some cases carbon dioxide. Microsoft Word - Welding_fuel_cells_final. Fiber Laser Welding of Fuel Cells. Laser Welding Fuel Cells. There are a number of welding applications. within a fuel cell that a fiber laser can be used. for: ·. Bi-polar...
• Combining 2-D and 3-D Laser Applications
  - based resonators to deliver reasonable wall-plug efficiency and a safe work environment at a low initial investment. Depending on the manufacturer, the resonator for a CO2 laser requires a mixture of helium, nitrogen, CO2, and carbon monoxide delivered at a pressure between 25 and 80 pounds per square...
• Control of Hexavalent Cr in Welding Fume (.pdf)
  electric welder that employed an inert gas mixture of 75% argon and 25%. carbon dioxide to blanket the work. A material safety data sheet (MSDS) for. the inert gas is attached to this report. Coupons (or "blanks") of 316. stainless steel were employed as the substrate upon which beads of 316. stainless...
• University of Waterloo Skip to the content of the web site.
  research in the physics department specializes in the applications of powerful industrial lasers that can produce high intensity beams and can cut or weld metals such as steel at speeds of more than six metres per minute. The most important of these is the carbon dioxide laser that operates...
• Batteries For Life
  aluminum tetrachloride in thionyl chloride. The current collector makes an electrical connection between the porous carbon cathode and the positive terminal of the battery. The can and cover are typically nickel-plated cold-rolled steel. The cell cover is welded to the cell can by a laser seam-welding...
• Cutting and Weld Preparation; The Many Faces of Plasma Cutting (.pdf)
  . It provides a high-quality cut, and it is required for mechanized cutting of material. thicker than 3 inches Carbon dioxide also can be used as an assist gas when cutting with. nitrogen plasma because it cuts most metals and provides good cut quality. Nitrogen/hydrogen and CH4 methane are two other types...
• Titanium
  also keeps aluminum alloys, specialty steels, and a number of hard to find alloys in stock. Industries served include the aerospace, defense, and chemical industries. Flat bars and blocks are also available in ferrous alloys such as carbon, stainless and tool steels, and in cobalt and nickel based...
